Designers are often positioned as mediators or interpreters working between disciplines and stakeholders to frame and address problems. This quality is particularly desired when a product transitions from one implementation to another. Translational designers assist this process through critical activities such as navigating differing domain knowledge and balancing conflicting values or cultures between stakeholders. We argue that the primary outcome of translational design is not necessarily an artifact but the translation of knowledge across disciplines for decision-making. Our research explains and shows how information visualization can translate meaning within a group of experts seemingly familiar with the same topic and between a group of experts with differing expertise.

Though recent research has explored the design of rich screen reader visualization experiences, accessible visualizations for blind and low vision users remain rare on the web. While some visualization toolkits offer accessible solutions, toolkit-specific implementations can present idiosyncratic user experiences that limit learnability. We present Olli, an open source library that converts visualizations into a keyboard-navigable structure accessible to screen readers. Using an extensible adapter design pattern, Olli is agnostic to the specific toolkit used to author the visualization. Olli renders a chart as an accessible tree view following the HTML Accessible Rich Internet Applications (ARIA) standard. Olli helps visualization developers easily create accessible visualizations across visualization toolkits.
